Elanco PRRS vaccine licensed by USDAJune 27, 2018Prevacent PRRS vaccine, a modified-live respiratory vaccine effective in the reduction of porcine reproductive and respiratory syndrome (PRRS), respiratory form, in piglets aged 2 weeks or older, has been licensed by the USDA, reports Elanco Animal Health, a division of Eli Lilly and Co. PRRS causes disease in two forms: a respiratory form that weakens young pigs' ability to breathe and a more severe reproductive form that causes mass deaths in pigs during late pregnancy. Since its emergence in the late 1980s, the virus has cost the swine industry millions annually in respiratory disease in piglets and reproductive failure in sows. Current estimates place the cost at $560 to $660 million annually. "PRRS has grown to be a costly and challenging disease that is difficult to control at the local, regional, and national levels," said Chris Chavis, senior director with Elanco North America Food Animal Business. "We are eager to bring producers a new product to tackle this devastating disease." The vaccine is part of Elanco's Full Value Pigs line, which includes a portfolio of products that help to control specific enteric and respiratory diseases. The viral strain in Prevacent PRRS is "highly relevant" to today's swine operations, Elanco …
KSU researcher protects pigs against PRRS during reproductionDecember 1, 2017 Raymond "Bob" Rowland, Ph.D., professor of diagnostic medicine and pathobiology in the Kansas State University College of Veterinary Medicine, has created a way to protect swine offspring from porcine reproductive and respiratory syndrome (PRRS) virus during pregnancy. Rowland has found that mothers without the CD163 protein are resistant to the PRRS virus and give birth to healthy, normal piglets. The work appears in Nature's Scientific Reports. "We have created a protective shell against the PRRS virus during the reproductive phase of production," Rowland said. "The offspring does not become infected during pregnancy and is born a healthy piglet. During this critical phase of production, we have essentially ended a disease." The PRRS virus causes disease in two forms: a respiratory form that weakens young pigs' ability to breathe and a more severe reproductive form that causes mass deaths in pigs during late pregnancy. "The reproductive form not only has a tremendous economic impact, but also a psychological impact on people who work with pigs," said Rowland, who has spent more than 20 years studying the PRRS virus. "When we look at ways to control this disease, it really begins with reproduction. We want to keep this …
